Hey Brett, Good to see you still around. I stayed off site for a long time and also had a different alias years back and you often helped me way back.
This is a coach that I have bought but not yet picked up. Has 245/70/19.5 on it and is 34 ft and I have obviously not weighed it yet. It has 2 slides and is a Workhorse Chassis. The dealer is installing tires as part of the deal and will pay for the factory replacements and I had offered to pay the difference for a higher load range but his tire store, who I talked to, said the above. I do know I once went up a load range on an Expedition EL and it did turns better and did not sway as much when towing, but it had a much harsher ride and you could even feel paint stripes in road and did get old on a trip.
